What did Naota mean by this?

when its used in an anime, its typically representing that the character is still childish. Kids like sweet drinks and candy and dont appreciate the sour flavors until they grow up a bit. FLCL used this as well with the main character

Should I even finish this? I watched up until episode four before I just lost interest, does it get any better?

Not really. It's just something to watch if you're bored

Why would you go out of your way to drink something sour? That sounds gross. Unless he just means like grapefruit juice or something but that's more bitter than sour.

He doesn't like to eat pussy.
